What county is Bainbridge Island in?

Kitsap County, not King County. It is its own city. Seattle is across Puget Sound in King County.

That is why Google Maps “near Seattle” packing can confuse a first visit. Civic site: City of Bainbridge Island. We are the independent guide, not the city and not the DMO.

You still get here from Seattle on the Colman Dock ferry or you drive the Agate Pass Bridge from the Kitsap side. Getting here.

Population, size, and the name: more in this FAQ group. About this site if you wanted the publication, not the island.
